Ella is planting trees along her driveway, and she has 66 sycamores and 66 palm trees to plant in one row. What is the probability that she randomly plants the trees so that the two types of trees alternate? Express your answer as a fraction or a decimal number rounded to four decimal places.

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
